We were already pretty pumped for 'Falling Skies' third season, which is set to premiere with a two-hour installment on Sunday June 9, but the latest trailer really is out of this world. The new full-length preview for the TNT alien actioner produced by Steven Spielberg brings with it a more epic scope than anything seen on the series to date, along with new guest stars and our best look yet at the new aliens!

In this new trailer, not only do we get on the ground for some seriously epic battles, but the newest preview gives our first look at guest star (and ‘House‘ alum) Robert Sean Wilson as the previously unseen Charleston power-grid moderator Dr. Roger “The Rat King” Kadar and at Gloria Reuben, who plays Marina Perlata, a member of the resistance and aide to Tom Mason. Plus another previously unrevealed treat for sci-fi fans in the appearance of 'Battlestar Galactica' vet Michael Hogan!

You'll also catch our clearest visuals to date of the 2nd Massachusetts' new Vohm ally "Cochise" ('Hellboy's Doug Jones), a member of the race that descended in season 2 finale "A More Pefect Union." He even gets a horse! The third season of TNT’s alien drama also boasts former ’7th Heaven’ star Stephen Collins as surviving US President Benjamin Hathaway, but we haven't seen him yet.

You can check out the sci-fi-tastic trailer above, and tell us in the comments if you'll tune in for the June 9 premiere of 'Falling Skies' season 3!
